Graphite, also called plumbago or black lead, mineral consisting of carbon. Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets.
What is the chemical composition of graphite and diamond?
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals which have the same chemistry but different crystal structures are called polymorphs.
What graphite consists of?
Graphite consists of a ring of six carbon atoms closely bonded together hexagonally in widely spaced layers. The bonds within the layers are strong but the bonds between the layers are less in number and therefore are weaker.
What is diamond chemical formula?
Diamond Formula (repeating unit) C Strunz classification 1.CB.10a Dana classification 1.3.6.1 Crystal system Cubic.
Why is graphite slippery?
Graphite has delocalised electrons, just like metals. The forces between the layers in graphite are weak. This means that the layers can slide over each other. This makes graphite slippery, so it is useful as a lubricant .
What is chemical formula C?
Carbon (from Latin: carbo “coal”) is a chemical element with the symbol C and atomic number 6.
What is the symbol of diamond?
What is the symbolic meaning of a diamond? Diamonds have largely come to symbolize love and commitment. In the past, rings were without gemstones, but these days, wedding and engagement rings are often set with diamonds.
What is coal chemical formula?
The chemical formula of coal is reported as: C135H96O9NS. Coal is usually taken as 85% carbon based on dry mass. One tonne of oil equivalent is usually 1.5 t of black coal or 3 t of brown coal.
Is Ch a chemical symbol?
Chemical formula, any of several kinds of expressions of the composition or structure of chemical compounds. Thus, benzene is represented by the empirical formula CH, which indicates that a typical sample of the compound contains one atom of carbon (C) to one atom of hydrogen (H).
What is the chemical name for Ch?

Is chemical formula of?
A chemical formula (plural: formulae) is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−).
What do diamonds mean in the Bible?
Those who consider Diamond a spiritual stone see it as a representation of perfection. Its sheer strength has earned its associations with invincibility, courage, and strength.
Where is diamond found in India?
In India, Andhra Pradesh, Chhattisgarh, and Madhya Pradesh are the three states that produce diamonds. Among them, Madhya Pradesh accounts for about 90% of the total diamond resource of the country.
Is diamond a good conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won’t be flow of electrons That is the reason behind diamond are bad conductor electricity.
What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
Is coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
Is coal a tar?
Coal tar is derived from coal. It is a byproduct of the production of coke, a solid fuel that contains mostly carbon, and coal gas. Coal tar is used primarily for the production of refined chemicals and coal-tar products, such as creosote and coal-tar pitch.
What is the chemical symbol of K?
